像我们后端程序员做前端的话,有时候真不需要知道什么原理,直接塞就好了
我们选用基于hiprint 的vue-plugin-hiprint来打印
目的是为了实现点击某些行的数据,然后点击某个按钮直接弹出下面的打印

此链接 大佬是原创,我拿来总结梳理一下
插件进阶功能请移步: 链接

首先安装2个依赖

npm install vue-plugin-hiprint
npm i jquery --save-d
npm install vue-plugin-hiprint@0.0.55-beta3
这里是更新包,想获取最新包移步:https://github.com/CcSimple/vue-plugin-hiprint/blob/main/CHANGELOG.md

然后找到项目中的依赖文件夹node_modules/vue-plugin-hiprint/dist/中的print-lock.css文件,复制一份到自己项目的静态资源目录public下

然后在 public/index.html 中添加:

 <link rel="stylesheet" type="text/css" media="print" href="<%= BASE_URL %>print-lock.css">

然后 main.js 中引入 依赖

import { hiPrintPlugin } from 'vue-plugin-hiprint'
//引入一维码
import JsBarcode from "jsbarcode";Vue.use(hiPrintPlugin, '$pluginName')
import jquery from 'jquery'
Vue.prototype.$ = jquery

将下面的代码复制到自己项目中

methods: {//打印部分// 初始化init() {// 初始化 打印对象const hiprintTemplate = new this.$pluginName.PrintTemplate()this.hiprintTemplate = hiprintTemplate},// 获取打印机列表getPrinterList() {if (window.hiwebSocket.opened === false) {this.$notify.error('打印机客户端未连接')}// 模板对象获取const printerList_ = this.hiprintTemplate.getPrinterList()console.info(printerList_)},// 使用 hiPrintPlugin 控件打印confirmPrintPrint(row) {// 如果在 main.js 中设置了取消自动连接客户端 是获取不到打印机列表的！！！if (window.hiwebSocket.opened === false) {this.$notify.error('打印机客户端未连接，请点击右上角头像下载打印客户端')}// 这一句代码 如果打印出来有问题 可以尝试加进去，没有出现 则不用加// 初始化 providerthis.$pluginName.init({providers: [defaultElementTypeProvider()]})// 这一句代码 如果打印出来有问题 可以尝试加进去，没有出现 则不用加this.$pluginName.PrintElementTypeManager.buildByHtml(this.$('.ep-draggable-item'))// 清空原内容this.$('#printDivXm3').empty()// 不使用全局对象, 使用模版打印，在线设计模版：https://ccsimple.gitee.io/vue-plugin-hiprint/const hiprintTemplate = new this.$pluginName.PrintTemplate({template:{"panels":[{"index":0,"name":1,"height":297,"width":210,"paperHeader":49.5,"paperFooter":780,"printElements":[{"options":{"left":17.5,"top":87.5,"height":72,"width":550,"field":"dayincanshu","groupFooterFormatter":"function(t,e){return\"这里自定义统计脚信息\"}","groupFieldsFormatter":"function(type,options,data){ return [\"name\"] }","coordinateSync":false,"widthHeightSync":false,"columns":[[{"width":70,"title":"行号","field":"id","checked":true,"columnId":"id","fixed":false,"rowspan":2,"colspan":1},{"width":100,"title":"人员信息","checked":true,"fixed":false,"rowspan":1,"colspan":2},{"width":100,"title":"销售统计","checked":true,"fixed":false,"rowspan":1,"colspan":2}],[{"width":120,"title":"姓名","field":"name","checked":true,"columnId":"name","fixed":false,"rowspan":1,"colspan":1,"align":"left"},{"width":120,"title":"性别","field":"gender","checked":true,"columnId":"gender","fixed":false,"rowspan":1,"colspan":1},{"width":120,"title":"销售数量","field":"count","checked":true,"columnId":"count","fixed":false,"rowspan":1,"colspan":1},{"width":120,"title":"销售金额","field":"amount","checked":true,"columnId":"amount","fixed":false,"rowspan":1,"colspan":1}]]},"printElementType":{"title":"表格","type":"table","editable":true,"columnDisplayEditable":true,"columnDisplayIndexEditable":true,"columnTitleEditable":true,"columnResizable":true,"columnAlignEditable":true,"isEnableEditField":true,"isEnableContextMenu":true,"isEnableInsertRow":true,"isEnableDeleteRow":true,"isEnableInsertColumn":true,"isEnableDeleteColumn":true,"isEnableMergeCell":true}}],"paperNumberLeft":565.5,"paperNumberTop":819,"paperNumberContinue":true,"watermarkOptions":{"content":"vue-plugin-hiprint","rotate":25,"timestamp":true,"format":"YYYY-MM-DD HH:mm"}}]}})// 挂载打印内容hiprintTemplate.design('#printDivXm3')// 打印数据，要和 上面 panel 内的 field 参数一致const table = [{id: '我是条形码内容',name: '我是测试内容1',gender: '我是测试内容2'},{id: '我是条形码内容',name: '我是测试内容1',gender: '我是测试内容2'},]const contentToPrint = document.getElementById("contentToPrint");var dayincanshu = {// dayincanshu:this.dayincanshudayincanshu:table}hiprintTemplate.print(dayincanshu)},}

注意这个字段名要匹配,就ok 了
